→Part 3: Series and Parallel (with resistors)
'''Don't build circuit #6!! I will show it to you in class.'''
...but here is the rationale if you want to think about it. :
* We have a 5 Volt supply and a 10 Ohm Resistor.
* The resistor is rated at 1/4 of a Watt, or 0.25 Watts.
* P=I*V. P=I*5V.
* this amounts to a brief (and cautionary) demo of what a '''power rating''' is, and why it is important.
